Queen's Gambit Accepted Attacking Pinned Piece Chess Puzzles

In the Queen's Gambit Accepted, White often builds pressure after 1.d4 d5 2.c4 dxc4, and the motif of attacking a pinned piece appears when a defender cannot move because it would expose a more valuable piece or the king. A classic feature is a bishop or knight pinned on a file, diagonal, or against the queen, allowing the attacker to win material or break the center. For an intermediate player, this means looking for positions where the accepted c-pawn has drawn a piece away and created a tactical target behind it.
